Application filed July 19, 1908. Serial No. 508,317.

To all whom it may concern:

Be it known that I, NANCY Toozunn, a citizen of the United States, residing at Fitzgerald, in the county of Ben Hill, State of Georgia, have invented certain new and useful Improvements in Envelops; and I do hereby declare the following to be a full,

clear, and exact. description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in envelope and more particularly to the safety 't pe.

It has for its object the provision of a device of that kind provided with a pocket which is interposed between the frontand. back flaps and so arranged that it will be impossibleto obtain access to the pocket without mutilating the body of the envelop. Another object is the provision of a row ofstitching for securing one side and end of the pocket to the back flap, this construction preventing the pocketfrom being opened by steaming such as is frequently done when the parts are glued together.

With these and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claim; it being understood that various 0 changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of the specification :Figure 1 is a plan view of the blank from which the envelop is formed. Fig. 2 is a similar view showing the marginal strips at the edges of the front and back flaps folded over and also the flap constituting one side of the pocket folded over the marginal strip ofthe front flap. Fig. 3 is a similar view showin the side and end edges of the pocket flap stitched-to the front and back flaps. Fig. 4 is a plan view of the envelop completely folded. Fig. 5 is a longitudinal sectional view on the line 55 of Fig. 4. Fig. 6 is a-transverse SQCl'lOlltll view on the line 66 of Fig. 4.

Similar numerals of reference are employed to designate corresponding throughout.

The blank of which the device isrformed is designated by the numeral 5. The'front flap is designated by the numeral 6 and the parts back flap by the numeral 7. As shown in Fig. 1, the front flap 6 is somewhat less in length than the back flap 7 and approximately twice as great in width as the latter. That portion of the front flap6 which extends beyond the longitudinal edgeof the back flap 7 is of substantially the same size as the back flap and is designated by the numeral 8 and constitutes a pocket flap: The pocket flap is foldable over the inner face of the front flap 6 while the lon itudinalside of the front flap 6 remote from the pocket flap 8 is provided with a marginal strip 9 adapted to be folded over the 'free longitudinal side of the pocket flap 8, after the latter has been folded over the front flap 6, and secured thereto by a row of stitching 10, as clearly illustrated in Fig. 3. The opposite longitudinal sides of the back flap 7 are provided with marginal strips 11 and 12, of unequal widths. The marginal strips of the back flap are foldable over the inner face of the back flap and their outer surfaces are gunnned.

The free end of the front flap 6 is provided with a locking tongue 13, the length of which corresponds, approximately, to onefourth the length of the front flap 6. The

locking tongue 13 at its base has the same width as the front -fiap 6 and its opposite ends are inclined from the base to the outer side of the tongue. The tongue is foldable outwardly upon itself at substantially its longitudinal center as clearly shown in Fig.

3. The back flap 7 is provided on its free end with a sealing flap 14, which in width is approximately 0ne-half the width of the locking tongue 13. The sealing flap 14 is folded over the inner face of the back flap 7 and its outersnrface is gurrmned.

'In forming the envelop the pocket flap '8 is folded over the inner face of the front flap 6 after which the marginal strip 9 is folded over the free side of the back flap and is secured thereto by a row of stitching,'asbefore described. When the pocket flap is thus secured, the back flap is folded over the outer .face of, the pocket flap 8 until the base offthe'sealing flap 14 is in engagement with the locking tongue 13.,-
